Several people have posted on the famous hand in warm water trick whereby submerging a sleeping person's hand in warm water while asleep induces urination. Many people have claimed they have heard of this prank, but I want to know how many people have truly witnessed this in person.
I am also curious to know if anyone has any plausible hypothesis as to how it works. I understand the micturition reflex (urintation reflex) is a spinal reflex with regulation from higher brain centers, but how exactly the warm water would trigger the urination is of interest to me. Do you think the warm water evokes the spinal reflex or causes enough activation such that it overcomes the tonic inhibition from higher brain centers. I'm very curious to see what ideas people propose.

I've done this before, years ago, and it worked like a charm. My friend, we'll call him Soggy, would pass out on the couch during parties after quite a lot of beer.
One evening we microwaved a large bowl of water and placed Soggy's hand in it. An hour later we checked and Soggy was well, soggy. We carefully removed the bowl of water and to this day Soggy just thinks he can't hold his beer. :)
Note: Always make sure it's not your couch!
I'm pretty good with science, but I'm not up on why this works, so I can't help with the second part of your question.

My friend tried it on me and didn't work. I think it depends on the person and their sleep habits.
